Be it known that we, RALPH H. PERRY and. HARMON J. COOK, citizens of the United States residin at Torrington, in the county of llitchfiel cut, have inventedcerta-in new and useful Improvements in- Swagers with W edge Motion, of'which the following is a description,

reference being bad to the'accompanying drawing and to the figures of. reference marked thereon. j

The invention relates to new and useful improvements in swaging machines, and more particularly to a. swaging machine having opposed cooperating swaging dies which are adapted for swaging particularly wir'estock, small rods, and the like.

An object of the invention is to provide a swaging machine with a lurality of airs of swaging dies, which ies rotate a out the stock being swaged and are simultaneously actuated to swage the stock during their rotation. v

A further object of the invention is to provide a swaging machine of the above type wherein the actuating means for the swaging dies is free to; travel so that the.

working position of the-dies is caused to travel about the stock during the swaging thereof. I

A still further object of the invention is to providea swaging machine of the above type with means for varying the radial working position of the dies whereby blanks may be swaged todifi'erent sizes.

A still further object of the invention is to provide a swaging machine of the above type with radially moving dies and wear plates therefor, which can be readily replaced after they become worn.

A still further object oi the invention is to provide wedges for shifting the radial working position of the dies and'means for adjusting the wedges which is simple-in construction and which may be readilymanip- State of Connectithe accompanying 2 is. a front view thereof, Fig. 3 is a section Fig l;

he invention in' directed to a swaging machine having a lurality of pairs 0 co-operation swai'ng The dies in each pair are arranged on opposite sides or substantially so, of the stock being swaged. These dies are all mounted in'a rotatable head and are so, constructed as to be moved radially of the head in sw'aging the stock. Actuating means is view of the wedge rod provided for simultaneously moving all ofthe swaging dies into engagement with the stock. This actuating means operates intermittently on the swag'ing d1es and is preferably in the form of rollers mounted loosely in a spacing ring which holds the rollers a predetermined istance apart, but at the same time permits therollers to free- 1y rotate and to travel bodily about the center of the 'rotatin head. The'traveling of the'rollers about t e center of the rotating head causes the traveling of the working position of the rotating dies and thus it is that the stock may be swaged from every angle and a very perfectly rounded article produced. The fswaging diesare operated by backerswhich engage the rollers and between the hackers and the swaging on the line 3-3 ofits broadest aspect is ies..

dies are wedges which may be simultaneous- -ly moved in or out manually for changing the radial working position of the swaging dies so-as to swage blanks to varying sizes. The swaging dies are mounted in radial grooves in the rotating head and wear'plates are provided which may be readily removed and replaced on which said swaging dies reciprocate. A. hardened wear'ring is also provided in the stationary housing within which said supporting head rotates. This hardened rin is concentric to the axis of rotation of e head, and forms an abutment for the rollers which operate the swa 'ng dies. As the swagin die passes a r0 ler, it turns it slightly an causes it to roll along the hardened ring and this is what causes the rollers to travel in the same direction as the rotating head, but of course,

at a much slower spec Referring now to the drawings in detail, the invention comprises a base 1 supportlng the spaced standards 2 and 3, the former supporting "the hollow stationa housing 4 in which is rotatably mounted t e spindle 5, the outer end 6 of which is supported by 'thestandard 3. Spindle 5 is driven by the pulley 7 keyed of fixed thereto. Sa1d spinfaces of the rack, the inner opening being sufiiciently large to permit the rolls to project sufficiently to operate the swagmg dies as hereinafter described. This roll rack 9 then, merely acts as a rollspacer or keeper,

the rolls being free to rotate on the inner peripheral face of the ring 8, thus elimin" ating wear of the roll rack. The roll rack 9 makes a loose fit in its seat or bore of the housing 4 and is freeto rotate therein so as to permit the die operating members or rollsto shift circumferentially in the head.

The front portion of the spindle 5 is formed' with an enlarged head 11 as above noted and said head is provided with spaced slots or guideways 12, 13, 14 and 15. The number of such slots depends upon the number of pairs of i dies desired, the number varying from 2, 4 or 6. It has been found that four dies afford a much more desirable swaging action than two dies.

In one form, these slots are designed with internal shoulders 16 and 17 formed with dowel-pin recesses or bores 18. The shoulders are easily formed-by forming the guideways narrower .at the rear portion, of the head 11 as at 19. The front faces of the segments20, 21, 22 and 23, which are formed by the radial intersecting slots or guideways 12, 13, 14 and 15 are preferably cut away as at 16', 17, 18' and 19' and formed with screw holes to receive a front plate or cover 20' formed with acentral opening for the insertion of the wire or stock between the dies. The slow 12 to 15 form guideways forthe reciprocable dies and backers or followers. In order to prevent excessive wear of these slots, they are preferably lined These bores in the roll rack open onto thefinner and outer peripheral spindle 5. This with wear pieces. The preferred construction of the wear blocks is illustrated in Fig. 5. The block 24 is formed somewhat U-shaped with atransverse slot 25 through both legs thereof. The faces of these slots 25 are beveled as at 26, 27,, 28 and 29 to form seats for joining beveled faces of two additional wear blocks 30 and 31 which are also substantially ,U-shape. The wear block 30 has the beveled faces 32 and 33 while the block 31 has the beveled faces 34 and 35. By inclining these faces as described, the wear blocks make a neat and close fit at the converging point of the radial guideways, as clearly shown in Fig. 3. The block 24 is formed fwith the rearwardly projectin dowel pins 36 and 37 and the blocks 30 and 31 are formed with the rearwardly projecting pins 38 and 39. These respective pins fit snu ly in the holes formed in the shouldered aces 16 and 17 of the slots 12, 13, 14 and 15. In addition, each Wear block is provided with a slot through which pass the wedges as hereinafter set forth. The block 24 is provided with the upper and lower slots 40 and 41, respectively, while the blocks 30 and 31 are formed with the slots 42 and 43, respectively. Block 24 is like wise formed with a central threaded bore 44.

The dies 45, 46, 47 and 48 are arranged in the guideways and slide on the rear blocks. The backers or followers 49, 50, 51 and 52 are likewise arranged in the guide- Ways and slide on wear blocks. Between these backers and their respective dies are disposed the wedges 53, 54, 55 and 56, as is well known in the art. These wedges pass rearwardly as shown in Fig. 1, and are perforated at their inner ends to loosely receive pins 57, 58, 59 and 60 projecting from a wedge opening yoke 61.

This yoke 61 is keyed to the inner end of a wedge operating rod 62 which extends rearwardly through the inner bore of the oke slides in the slotted portion of the spindle and to this end is provided with four radial arms 63, 64, and 66 which fit in"the slots 12, 13, 14 and 15 to prevent rotation of the yoke relative to the spindle.

The outer end of the rod 62 projects beyond the spindle 6 and is threaded .to form an adjustable connection with an operating lever 63. This lever is pivoted to stand ard 3 at 64'. The upper end of the lever is furcated as at 65 to engage pins 66 and67 projecting outwardly from a plate 68 loosely fitting over the threads of rod 62. This plate is held in adjusted position on rod 62 by means of the nuts 69 and 70 disposed on either side of the plate. The lower end of lever 63 is formed with an elongated slot 71 through which passes a threaded rod 72 screwed into the standard 3. The adjusting nuts 73 ad 74 hold'the lever-63in its position of adjustment.

For the purpose of supplying lubricant to'the face of the dies, internally to form a conduit 74 through which oil may be pumped by means of a connection to its outer threade end. This conduit 74 extends the'entire length of the rod and communicates with an enlarged recess 75 which telescopingly weaves a sleeve 76 bored as at 77 and threaded at its extreme end to thread into the hole 44 of the ing the dies simultaneously inwardl ing blows by the wear plate 24. By this construction, the lubricant is conducted to the faces of the dies and the wire stock as it is being swaged. The front face of the head 4 is enclosed by a plate 78 attached thereto by screws 79 and'provided with a central recess 80. This conduit also permits the wire stock to extend through the spindle if desirable.

fect the desired swaging action. he dies and backers are thrown immediately outwardly after they have assed over a roll, by centrifugal force. en the backers pass over the suceeding roll, the are again forced inwardly as before. In t is manner, the wire stock is given a succession of swagdies which are arranged about the circumference of the stock, so that a true round swaging is effected, although we do not wish to be limitednecessarily t0 round-swaging.

Since the die operating rolls are free to rotate within the head, their positions are constantly shifting as the head rotates, so that the dies are operated at constantly varying points about the circumference of the round stock. This construction also insures a truerround swage, free of fins or ribs.

When it is desired to shift the radial working position of the .dies to give the finished article a greater or less diameter, the wedge operatlng, rod is adjusted !by means of the lever 63, to slide the oke .61 inwardly or outwardly as is evi ent.

During this sliding movement of the yoke. the sleeve 76 telescopes within the recess 7 5 of the rods 62 so that the discharge of oil to the die faces 'is not interrupted.

It is obvious that minor changes ma be made in the details of construction an the the rod 62 is bored.
